CEL - P0100 - Volume Air Circuit Malfunction
Ok, not too much of a n00b here but I can't figure this out. I'll try to provide as much information as possible. Need any other stuff just ask, I should know.
1995 Car, 1990 6-bolt motor, 1995 2G head
Just got the car running on the newly built motor so this problem is kind of a big problem for me. Got a Check Engine Light obviously. Through DSMlink I see P0100 Volume Air Circuit. This is causing to car to run VERY rich, stutter, pop, and buck. Obviously this can't be happening with a brand new motor because I don't want to wash the rings out.
Checked TPS....its fine.
Checked for vacuum leaks...none.
Replaced the 2G MAS...same thing.
Some information that may help:
-Motor has maybe 3 miles on it so far
-Running DSMlink (as stated above)
-Sheet Metal Intake Manifold so there is no MDP Sensor on the car
-Have DSMlink set for the PLX to read off the MDP signal
-Car idles at first mid 14s and then goes from 10.5s to RICH on my PLX-M300.
-FIC 650s/walboro255/Fuel Pressure Regulator/stock fuel rail and lines/no rewire.
DSMlink settings:
-I believe its called the "global" and that is at 180 and all other settings are at 0 right now.
Going to make a boost leak tester some time this week and try that out but that would have to be one heck of a boost leak huh?
Thoughts? Ideas?

this might seem dumb but are you running a gm maf or stock, i had the same problem with mine and it kicked my ass for a few hours till i realized my maf was unpluged, might want to double check although im sure you alread have...

i don't think he's running a gm maf. He stated above that he replaced his 2g mas. I don't think he would be running both. I could be that if the 2nd 2g mas was used, it also could be bad. Replace the 2g mas off a running eclipse to see if you still have that problem.

Thanks for the replies guys, pretty sad there are more here then DSMtalk and DSMtuners...
Yea I tried another MAS (no don't have a GM setup) and I need to try another. Checking wire continuity needs to be checked as well.
